der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung bereitzustellen, die eine unbeabsichtigte Differenz zwischen den Saugrohrdrücken ausschließt. Ferner liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung bereitzustellen, durch die Toleranzen der Drosselorgane und Unterschiede der Saugrohrtrakte zumindest in einigen Betriebsmodi kompensierbar sind. Die Aufgabe wird jeweils gelöst durch die Merkmale der unabhängigen Patentansprüche, wobei weitere Ausgestaltungen der Erfindung den Unteransprüchen entnommen werden können.Of the Invention is in particular the object of a generic device to provide an unintended difference between the Saugrohrdrücken excludes. Furthermore, the invention has the object, a generic device to provide, by the tolerances of the throttle bodies and differences the Saugrohrtrakte at least in some operating modes compensated are.

Die Erfindung geht aus von einer Vorrichtung mit einer Einheit zum Betätigen einer Brennkraftmaschine mit zumindest zwei, jeweils einer Gruppe von Zylindern zugeordneten Saugrohrtrakten, wobei jedem der Saugrohrtrakte wenigstens ein unabhängig einstellbares Drosselorgan zum Einstellen eines Saugrohrdrucks des jeweiligen Saugrohrtrakts zugeordnet ist.The The invention is based on a device with a unit for actuating a Internal combustion engine with at least two, each of a group of cylinders associated Saugrohrtrakten, wherein each of the Saugrohrtrakte at least an independently adjustable Throttling element for adjusting an intake manifold pressure of the respective Saugrohrtrakts is assigned.
Es wird vorgeschlagen, dass die Vorrichtung zumindest ein Druckausgleichsmittel zum Angleichen der Saugrohrdrücke in zumindest einem Betriebsmodus umfasst. Dadurch kann in dem Betriebsmodus, sofern dies gewünscht ist, ein Druckausgleich zwischen den Saugrohrtrakten erreicht werden. Druckdifferenzen, die sich beispielsweise durch Toleranzen in den Drosselorganen oder durch asymmetrische Füllungsbedingungen einstellen könnten, können durch einen Druckausgleich vermieden werden.It It is proposed that the device has at least one pressure compensation means for equalizing the intake manifold pressures in at least one operating mode. As a result, in the operating mode, if desired is to be achieved, a pressure equalization between the Saugrohrtrakten. Pressure differences, for example, by tolerances in the Adjust throttle bodies or by asymmetric filling conditions could, through a pressure equalization can be avoided.
Obwohl die erfindungsgemäße Vorrichtung prinzipiell im Zusammenhang mit jeder, dem Fachmann als sinnvoll erscheinenden Brennkraftmaschine einsetzbar ist, ist der Komfortgewinn durch eine erhöhte Laufruhe, insbesondere im Zusammenhang mit Kraftfahrzeugmotoren, deutlich spürbar.Even though the device according to the invention in principle in the context of any one that appears appropriate to the person skilled in the art Internal combustion engine is used, the comfort gain is due to increased smoothness, especially in connection with motor vehicle engines, clearly noticeable.
Die einem Saugrohrtrakt zugeordnete Gruppe von Zylindern kann jede, dem Fachmann als sinnvoll erscheinende Anzahl von Zylindern umfassen. Aus Gründen der Laufruhe können besonders vorteilhaft drei oder mehr Zylinder zu einer Gruppe zusammengefasst sein, deren Zündzeitpunkte gleichmäßig über einen Arbeitszyklus der Brennkraftmaschine verteilt sind. Die Zylinder einer Gruppe können auf einer Zylinderbank liegen oder auch über zwei Zylinderbänke verteilt sein.The A group of cylinders associated with a suction duct can be any include the expert appear reasonable number of cylinders. Out establish the smoothness can particularly advantageous three or more cylinders combined into one group be, their ignition timing evenly over one Duty cycle of the internal combustion engine are distributed. The cylinders a group can lie on a cylinder bank or distributed over two cylinder banks be.
Ist das Druckausgleichsmittel als Druckausgleichsöffnung zwischen den zumindest zwei Saugrohrtrakten ausgebildet, kann ein unmittelbarer und schneller Druckausgleich ermöglicht werden. Durch eine steuerbare Verschlussklappe zum Öffnen und Schließen des Druckausgleichsmittels kann der Druckausgleich gezielt in bestimmten Phasen ermöglicht oder verhindert werden. Prinzipiell sind auch Ausgestaltungen der Erfindung denkbar, in denen der Druckausgleich indirekt über einen Regelkreis erfolgt.is the pressure compensation means as a pressure equalization opening between the at least Two Saugrohrtrakten trained, can be a more immediate and faster Pressure equalization allows become. By a controllable flap for opening and closing the Pressure compensation means, the pressure compensation targeted in certain Phases enabled or prevented. In principle, embodiments of the Invention conceivable in which the pressure compensation indirectly via a Closed loop.
Ist zumindest eine der Gruppen von Zylindern abschaltbar, können durch das erfindungsgemäße Druckausgleichsmittel die Vorteile der abschaltbaren Zylinder mit einer symmetrischen Last im Vollmotorbetrieb verbunden werden. Prinzipiell sind jedoch auch Kraftfahrzeugmotoren mit mehreren unabhängigen Saugrohrtrakten und Drosselorganen denkbar, die keine abschaltbare Gruppe von Zylindern umfassen.is At least one of the groups of cylinders can be switched off the pressure equalizing agent according to the invention the advantages of turn-off cylinder with a symmetrical Load be connected in full engine operation. In principle, however also motor vehicle engines with multiple independent Saugrohrtrakten and Throttling devices conceivable that no deactivatable group of cylinders include.
Differenzen in den Saugrohrdrücken, die durch Unterschiede bzw. Toleranzen zwischen Aufladegeräten bedingt sind, können durch das erfindungsgemäße Druckausgleichsmittel vermieden werden, wenn den zumindest zwei Saugrohrtrakten jeweils ein solches Aufladegerät zum Erhöhen des Saugrohrdrucks zugeordnet ist. Als Aufladegerät kommt insbesondere ein Kompressor oder ein Turbolader in Betracht.differences in the intake manifold pressures, due to differences or tolerances between rechargers are, can by the pressure equalizing agent according to the invention be avoided if the at least two Saugrohrtrakten respectively such a charger to increase associated with the intake manifold pressure. As a charger comes in particular a compressor or a turbocharger into consideration.
Ist die Einheit dazu vorgesehen, durch das Öffnen des Druckausgleichsmittels einen Druckausgleich zwischen den Saugrohrtrakten zu erzeugen, wenn die Saugrohrdrücke in beiden Saugrohrtrakten stark durch die Drosselorgane gedrosselt sind, können Toleranzen der Drosselorgane vorteilhaft über das Druckausgleichsmittel ausgeglichen werden. Unter „vorgesehen" soll in diesem Zusammenhang auch „ausgelegt" und „ausgestattet" verstanden werden. Als „stark gedrosselt durch eines der Drosselorgane" soll ein Saugrohrdruck bezeichnet werden, wenn der Saugrohrdruck in einem Wertebereich liegt, der einer Motorlast unterhalb von 30% der Volllast entspricht.is the unit provided by opening the pressure equalizing means to create a pressure equalization between the Saugrohrtrakten, when the intake manifold pressures throttled strongly in both Saugrohrtrakten by the throttle bodies are, can Tolerances of the throttle body advantageous over the pressure compensation means be compensated. Under "provided" should in this context also understood as "designed" and "equipped". As "greatly throttled through one of the throttle bodies "should An intake manifold pressure can be referred to when the intake manifold pressure in a Value range, that of an engine load below 30% of the full load equivalent.
Weitere Vorteile sind erreichbar, wenn die Einheit dazu vorgesehen ist, durch das Öffnen des Druckausgleichsmittels einen Druckausgleich zwischen den Saugrohrtrakten zu erzeugen, und wenn eine Lastanforderung der Brennkraftmaschine einen Schwellenwert übertrifft. Dadurch können Differenzen zwischen den Luftwegen der Ansaugluft ausgeglichen werden, die insbesondere nahe der Volllast der Brennkraftmaschine zum Tragen kommen.Further Benefits are achievable if the unit is intended to by opening the pressure compensation means a pressure equalization between the Saugrohrtrakten to generate, and when a load request of the internal combustion engine exceeds a threshold. Thereby can Differences between the airways of the intake air are compensated in particular close to the full load of the internal combustion engine for carrying come.
Ist die Einheit dazu vorgesehen, durch das Öffnen des Druckausgleichsmittels einen Druckausgleich zwischen den Saugrohrtrakten zu erzeugen, wenn die zumindest zwei Gruppen von Zylindern im gleichberechtigten Betrieb sind, können ungewollte Druckdifferenzen sicher vermieden werden. Als „gleichberechtigter Betrieb" sollen hier insbesondere Betriebsarten bezeichnet werden, in denen die Gruppen von Zylindern, die an die Saugrohrtrakte angeschlossen sind, ein gleiches Drehmoment erzeugen, bzw. Betriebsarten, in denen ein gleiches Druckniveau in den Saugrohrtrakten erforderlich ist. Ferner kann im gleichberechtigten Betrieb, und zwar insbesondere unter Volllast, erreicht werden, dass die Druckwellen der beiden Saugsysteme bzw. Saugrohrtrakte zur passiven Steigerung der Zylinderfüllung ausnutzbar sind, und zwar insbesondere dann, wenn die beiden Gruppen von Zylindern phasenverschoben betätigt werden. Es ist dann eine Saugrohrregisterung unter Volllast möglich.is the unit provided by opening the pressure equalizing means to create a pressure equalization between the Saugrohrtrakten, when the at least two groups of cylinders on an equal footing are, can unwanted pressure differences can be safely avoided. As an equal Operation "should In particular, operating modes are referred to, in which the Groups of cylinders connected to the intake manifolds, generate the same torque, or modes in which a the same pressure level is required in the Saugrohrtrakten. Furthermore, can on equal terms, and in particular under full load, be achieved that the pressure waves of the two suction systems or Saugrohrtrakte for passive increase of the cylinder filling exploitable are, especially if the two groups of cylinders out of phase become. It is then possible Saugrohrregisterung under full load.
Ferner geht die Erfindung aus von einem Verfahren zum Betätigen einer Brennkraftmaschine mit zumindest zwei, jeweils einer Gruppe von Zylindern zugeordneten Saugrohrtrakten, wobei jedem der Saugrohrtrakte wenigstens ein unabhängig einstellbares Drosselorgan zum Einstellen eines Saugrohrdrucks des jeweiligen Saugrohrtrakts zugeordnet ist.Further the invention is based on a method for actuating a Internal combustion engine with at least two, each of a group of Cylinders associated Saugrohrtrakten, each of the Saugrohrtrakte at least one independently adjustable throttle body for adjusting an intake manifold pressure of associated with respective Saugrohrtrakts.
Es wird vorgeschlagen, dass in zumindest einem Betriebsmodus zumindest ein Druckausgleichsmittel zum Angleichen der Saugrohrdrücke geöffnet wird. Dadurch kann verhindert werden, dass in dem entsprechenden Betriebsmodus eine ungewollte Druckdifferenz zwischen den Saugrohren herrscht.It It is proposed that in at least one operating mode at least a pressure equalizing means is opened to equalize the intake manifold pressures. This can prevent that in the corresponding operating mode an unwanted pressure difference between the suction pipes prevails.
In einer Weiterbildung des erfindungsgemäßen Verfahrens wird vorgeschlagen, dass das Druckausgleichsmittel zum Erzeugen eines Druckausgleichs zwischen den zumindest zwei Saugrohrtrakten geöffnet wird, wenn die zumindest zwei Gruppen von Zylindern mit gleicher Last betrieben werden.In A development of the method according to the invention is proposed that the pressure compensation means for generating a pressure equalization is opened between the at least two Saugrohrtrakten, if the at least two groups of cylinders are operated with the same load.
